There are several ways to make a flowchart. Originally, flowcharts were created by hand using pencil and paper. Before the advent of the personal computer, drawing templates made of plastic flowchart shape outlines helped flowchart makers work more quickly and gave their diagrams a more consistent look. Today, flowcharts are typically created using flowchart software.

Flow charts are easy-to-understand diagrams that show how the steps of a process fit together. American engineer Frank Gilbreth is widely believed to be the first person to document a process flow, having introduced the concept of a “Process Chart” to the American Society of Mechanical Engineers in 1921.
